My invention has for its object to provide cured to the spindle 2 by means of suitable a device for dispensing finely divided manuts 11 that are located on shanks of the blades terial, such as powdered material, more or which extend through the spindle 2. Thus less amorphous and compactible in its characthe planes of the blades 10 may be varied ter. In the dispensing of such material it has in their angular relation to the shaft 2 so as to been found diflicultto dispense uniform quanvary the downward movement of the matetities of the material owing to its compactirial or to hold the material as against compacbility. Also, as is well known in connection tion at the bottom of the cylinder 1 by reason with a great many forms of powdered maof the weight of the material in the cylinder 1. 1O terial, the compactibility is dependent upon The lower end of the cylinder 1 is provided 50 atmospheric conditions, particularly as to with means for dispensing material at a rate humidity, with the result that a very slight that corresponds to the rate of rotation of amount of dampness will cause increased the spindle 2. The disc 15 covers the lower compaction. The invention has for its object end of the interior of the cylinder 1 and is 15 to produce a uniform degree of compaction of connected to the spindle 2. The disc 15 is promaterial located within a confined space. vided with a hub 16 that fits on the lower end The invention may be contained in devices oi the spindle 2. The hub 16 projects into and used fora great variety of purposes. To ilbearswith the plate 1.

The material is maintained in a loose condition by means of the blades 10, and, as the disc 15 rotates, the openings 17 are filled. At one side of the cylinder I have provided a paddle wheel 25 having paddles 26 that are rotatably supported on a shaft 27 that may be secured in the wall of the cylinder 1. The paddle wheel 25 is so located that-its paddles may wipe the surface or" the disc 15 in the regions of the openings 17. The spindle 2 is provided with pins 28 that protrude from the shaft so as to engage the paddles 26 and cause rotation of the paddle wheel 25 as each of the openings 17 passes beneath the paddle wheel 25. By this wiping movement of the paddle wheel 25, the material is compacted into the openings 17 by the movement of the lowermost paddle 26 and by th movement of the disc 15. If desired, the paddles 26 of the pat-isle wheel 25 may be formed of a fienible m terial, such as rubber, so that the wiping action of the paddles 26 will have a more compacting effect upon the material located within the openings 17 of the disc 15. Thus, there is produced a wiping movement in a direction opposite to that in which the disc 15 is moved by the rotation of the spindle 9- which causes the compacting operation to quickly pass over the entire length of the opening 1'? and thus produce a downward and lateral movement of the material into each of the openings 17. The portion or" the disc 15 having the'material thus compacted by the paddle wheel 25 is conveyed to a point beneath the block 18 where the material is discharged through the opening 19 by the contact of an ejecting means located in the block 18. In the form or construction shown in the figures, a weighted ball 20 is located within the block 18 which readily rolls over the disc 15 as it rotates and thus continuously agitates the material that may be located within the recess 21 formed in the block. The weight of the ball 20 is sufiicient to discharge the compacted material from the openings 17 as they pass over the opening 19.

I claim:

1. In a dispensing device, a container having opening, a block located above the said opening, a disc movable beneath the said block and having openings adapted to register with the opening in the container, a spindle connected to the said disc'for rotating the disc and having blades for controlling the 'inoveinent of the material dispensed towards the said opening, a paddle wheel having pad dies adapted to make contact with the disc, the said spindle having fingers for engaging the paddle wheel to cause the rotation of the paddle wheel and movement of the paddle of the paddlewheel against the disc and in a direction opposite to that in which the disc IIIOVGS.

2. In a dispensing device for dispensing material, a container having an opening, a movable member located in the container having an openin adapted to register with the said opening of the container to permit the material to escape from the opening in the movable member, means for operating the movable member, a paddle, means for moving the paddle in the direction opposite to that in which the movable member is moved to produce registration of the openings, the paddle operating to wipe the material into the opening in the movable member.

3. In a dispensing device for dispensing material, a container having an opening, a movable member located in the container having an opening adapted to register with the said opening of the container to permit the material to escape from the opening in the movable member, means for operating the movable member, a paddle,ineans for moving the paddle in the direction opposite to that which the movable member is moved to *oduce registration or" the openings, the padd e operating to wipe the material into the opening in the movable member, and a fixed member covering the said opening in the container to prevent material escaping through the said openings in the container and the movable member.

In witness whereof I havehereunto signed my name to this specification.
